Answer:
"a" must be negative
Step-by-step explanation:
The slope between points (-1, 1) and (1, -1) is a minimum of (-1-1)/(1-(-1)) = -1.
The slope between points (1, -1 and (3, -4) is a maximum of (-4-(-1))/(3-1) = -3/2.
Thus, as x increases, the slope is decreasing. In order for that to be the case, the value of <em>a</em> must satisfy a < 0.

Answer:
y = 112
z = 27
Step-by-step explanation:
Alright,
So we know that a straight line adds up to 180. And looking at the figure, it looks like 68 + y = 180 if you do some visualization.
So, we can already calculate y.
y = 180 - 68
y = 112
Now we find z. z here is represented in an expression. We can see that y and the expression z is in are congruent to each other which means they will equal each other. And since we know that y = 112, we know that the expression z is in is also equal to 112.
So we set up an equation like so:
112 = 3z + 31
And start to simplify:
81 = 3z
Finally we divide:
27 = z
Therefore, z is 27
